43 / 85 page ![]() STM32F101x8, STM32F101xB Electrical characteristics Doc ID 13586 Rev 13 43/85 On-chip peripheral current consumption The current consumption of the on-chip peripherals is given in Table 18. The MCU is placed under the following conditions: ● all I/O pins are in input mode with a static value at VDD or VSS (no load) ● all peripherals are disabled unless otherwise mentioned ● the given value is calculated by measuring the current consumption – with all peripherals clocked off – with only one peripheral clocked on ● ambient operating temperature and VDD supply voltage conditions summarized in Table 5. 5.3.6 External clock source characteristics High-speed external user clock generated from an external source The characteristics given in Table 19 result from tests performed using an high-speed external clock source, and under the ambient temperature and supply voltage conditions summarized in Table 8. Table 18. Peripheral current consumption Peripheral Typical consumption at 25 °C(1) 1. fHCLK = 36 MHz, fAPB1 = fHCLK/2, fAPB2 = fHCLK, default prescaler value for each peripheral. Unit APB1 TIM2 0.6 mA TIM3 0.6 TIM4 0.6 SPI2 0.08 USART2 0.21 USART3 0.21 I2C1 0.18 I2C2 0.18 APB2 GPIO A 0.21 GPIO B 0.21 GPIO C 0.21 GPIO D 0.21 GPIO E 0.21 ADC1(2) 2. Specific conditions for ADC: fHCLK = 28 MHz, fAPB1 = fHCLK/2, fAPB2 = fHCLK, fADCCLK = fAPB2/2, ADON bit in the ADC_CR2 register is set to 1. 1.4 SPI1 0.24 USART1 0.35 |
